 Imperfect debugging study of SRGM with fault reduction factor and multiple change pointMadhu Jain, T. Manjula and T.R. Gulati International Journal of Mathematics in Operational Research, 2014, vol. 6, issue 2, 155-175 Abstract: The present investigation deals with the software reliability growth models (SRGMs) with imperfect debugging, testing effort function (TEF) and fault reduction factor (FRF). FRF is basically defined as the net number of faults removed in proportion to the failures experienced. We propose a new scheme for constructing SRGM based on non-homogeneous Poisson process (NHPP). The concept of Weibull type testing-effort function with multiple change point has been incorporated. The main focus in the present investigation is to obtain mean value function which is further employed to explore the software reliability indices. The model parameters are estimated by least square and maximum likelihood estimation techniques. The optimal release policy based on cost, reliability and testing efforts is also suggested. Numerical results are given to illustrate the validity of analytical results. Keywords: software reliability growth models; non-homogeneous Poisson process; NHPP; imperfect debugging; testing effort function; TEF; fault reduction factor; change points; optimal release time.
